use psarc extractor gui 1.2, select pak23.psarc and extract all in the same dir (create pak23) of the huge archive (build/main/pak23) .. it works fine from external and then you can delete the file pak23.psarc

Because you can't. The external HDD needs to be Fat32 formatted to run the games on Multiman on a CFW PS3. And files > 4GB won't copy to Fat32.

So that pak23 file of 10GB that is within the folders of TLOU you gotta split up to separate files with PS3 Tool Collection PSARC GUI into a new pak23 folder (instead of that one 10GB file) and then copy that newly unpacked files in the pak23 folder right to the place where the one pak23 file before was. And get that original pak23 10GB file out of there. Its now copying overhere, will be testing in 20 mins on CFW 4.30 PS3. Should run above 4.20 what was said in Duplex NFO

I can confirm this is working with PS3 Tool Collection. Before this post was here, I tried with PSARC.exe through the Uncharted 2 tutorial as unpacking the PSARC file ain't a new trick, but that didn't work for me, the DOS screen crashed consantly unpacking that 10GB pak23 PSARC file.

PS3 Tool Collection and its PSARC GUI worked properly and the game runs fine! Cheers and game on

Thanks for your suggestion it worked fine from External used aldos tools to extract pak23.psarc file and created a folder called pak23 and put all extracted files in that folder job done. Rogero 4.3. It takes little more time than usual for loading be patient.
